Abstract
This utility model relates to a kind of big electric current miniature circuit breaker, including shell and setting operating mechanism in the enclosure, bimetal leaf, pull bar, bimetal leaf is arranged on operating mechanism side, one section of arcuate groove is formed on operating mechanism, pull bar one end is inserted in arcuate groove, the other end is hooked in outside bimetal leaf, on the lateral surface of shell, the position formation of corresponding pull bar and pull bar adaptation and length are more than the pull rod slot of pull bar, the two ends of pull rod slot form the handle hole of the bar shaped of through shell and double gold hole respectively, pull bar is arranged in pull rod slot, the two ends of pull bar are each passed through handle hole and double gold hole.This utility model provides certain activity space by shell to pull bar, thus releases owing to the width of operating mechanism is limited by pull bar, it is simple to improves the volume of moving contact, and then improves the rated current of big electric current miniature circuit breaker in the case of not changing enclosure volume.
Description
Technical field
This utility model relates to a kind of miniature circuit breaker, especially a kind of big electric current miniature circuit breaker.
Background technology
Miniature circuit breaker is most popular a kind of terminal protection electrical equipment in architectural electricity terminal power distribution.Existing
The width of miniature circuit breaker 1P is 1 modulus i.e. 18mm, and this volume also defines the volume of the structure within miniature circuit breaker,
The especially operating mechanism at moving contact place, in order to ensure the activity space of operating mechanism upper connecting rod, operating mechanism needs to drawing
Certain thickness conceded by bar, and make that the moving contact on operating mechanism can not do is blocked up, limits the rated current of miniature circuit breaker.
Summary of the invention
The purpose of this utility model is to solve above-mentioned technical problem, it is provided that a kind of constancy of volume, big big of rated current
Electric current miniature circuit breaker.
For achieving the above object, this utility model uses a kind of big electric current miniature circuit breaker, including shell with outside being arranged on
Operating mechanism in shell, bimetal leaf, pull bar, bimetal leaf is arranged on operating mechanism side, and operating mechanism is formed one section of arc
Shape groove, pull bar one end is inserted in arcuate groove, and the other end is hooked in outside bimetal leaf, the position of corresponding pull bar on the lateral surface of shell
Formation is more than the pull rod slot of pull bar with pull bar adaptation and length, and the two ends of pull rod slot form the behaviour of the bar shaped of through shell respectively
Making hole and double gold hole, pull bar is arranged in pull rod slot, and the two ends of pull bar are each passed through handle hole and double gold hole.
It is correspondingly formed 1 group on the two side of the pull rod slot that this utility model is further arranged to described shell or organizes card more
Block.Fixture block prevents pull bar from dropping out, and improves the Assembly stability of pull bar and pull rod slot, convenient installation.
This utility model is further arranged to the outside of described pull rod slot and arranges pull bar lid, covers in pull rod slot.Pull bar lid
Covering in pull rod slot, prevent pull bar from dropping out, pull bar lid generally uses paster, and it is convenient to paste.
This utility model is further set to the surrounding of pull rod slot and forms the square groove that a circle caves in, and pull bar lid is with square
Groove adaptation is covered on square groove.
The beneficial effects of the utility model are to arrange pull rod slot on shell, provide certain activity by shell to pull bar
Space, thus release owing to the width of operating mechanism is limited by pull bar, it is simple to improve the volume of moving contact, and then outside not changing
Improving the rated current of miniature circuit breaker in the case of shell volume, and pull bar is installed from shell, the front tension bar compared is movable
Assign on operating mechanism and bimetal leaf the most convenient stable, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the explosive view of this utility model embodiment.
Fig. 2 is the schematic diagram removing a side body of this utility model embodiment.
Detailed description of the invention
As shown in Figure 1 and Figure 2, specific embodiment of the utility model is a kind of big electric current miniature circuit breaker, including shell 1
With the operating mechanism 2 being arranged in shell 1, bimetal leaf 3, pull bar 4, bimetal leaf 3 is arranged on operating mechanism 2 side, operation
Forming one section of arcuate groove 21 in mechanism 2, pull bar 4 one end is inserted in arcuate groove 21, and the other end is hooked in outside bimetal leaf 3, shell 1
Lateral surface on the position of corresponding pull bar 4 form and length adaptive with pull bar 4 pull rod slot 11 more than pull bar 4, pull rod slot 11
Two ends form the handle hole 12 of bar shaped of through shell and double gold holes 13 respectively, the two side of pull rod slot 11 is correspondingly formed two
Group fixture block 14, pull bar 4 is arranged on sliding in pull rod slot 11, and fixture block 14 blocks pull bar 4 and prevents pull bar 4 from dropping out, and the two ends of pull bar 4 are divided
Not Chuan Guo handle hole 12 and double gold holes 13 be inserted in arcuate groove 21 in and be hooked in outside bimetal leaf 3, pull rod slot 11 surrounding forms one
The square groove 15 that circle caves in, square groove 15 arranges the pull bar lid 16 of adaptation, and pull bar lid 16 covers on square groove 15.
